Teachers should be licensed and will face the sack if they fail to pass checks on their abilities, the Labour party has said.
Shadow education secretary Tristram Hunt said he wants teachers to be reviewed every few years to improve standards in England's state schools.
A similar proposal was floated by the previous Labour government - and dubbed "classroom MoTs" by former schools secretary Ed Balls - but was opposed by some unions and dropped before the 2010 general election.
Mr Hunt told the BBC: "Just like lawyers and doctors they should have the same professional standing which means re-licensing themselves, which means continued professional development, which means being the best possible they can be.
"If you're not a motivated teacher - passionate about your subject, passionate about being in the classroom - then you shouldn't really be in this profession."
Mr Hunt went on to tell The Times: "If we want to re-professionalise the teachers it would be crazy not to do it. If teachers are not re-licensed they will not be allowed to teach."
The Opposition has previously said it would insist on all teachers having Qualified Teacher Status, with staff already working in academies given a deadline to acquire a formal qualification.
A Conservative Party spokesman said the Government was willing to look any proposals which will "genuinely improve the quality of teaching".
He said: "We have already taken action by allowing heads to remove teachers from the classroom in a term, as opposed to a year previously, and scrapping the three-hour limit on classroom observations.
"We are improving teacher training, expanding Teach First and allowing heads to pay good teachers more. Thanks to our reforms, a record proportion of top graduates are entering the profession.
"Fixing the schools system so young people have the skills they need is a key part of our long-term economic plan."
